What is indicated by indicator dye problems on carpets?

Indicator dye problems on carpets are specifically associated with the use of extreme pH chemicals during the cleaning process. These dyes are sensitive to changes in pH, and when highly alkaline or highly acidic cleaning agents are applied, they can cause the dye to change color or fade, resulting in discoloration of the carpet.

In many cases, indicator dyes are specifically used in carpets to assess the effectiveness of cleaning. When extreme pH levels are used, they can disrupt the bond and stability of these dyes, leading to noticeable and often irreversible damage. Unlike issues stemming from moisture damage, excessive cleaning, or sun exposure, which tend to have different underlying causes, problems with indicator dyes are directly tied to the chemical composition of the cleaners utilized.
